GARBAGE-INCINERATOR FOR FURNACES.

Specification of Letters Patent.

Patented Dec. 5, 1916.

To all whom it may concern Be it known that I, GEORGE F. WEN'rz, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented a new and useful Garbage-Incinerator for Furnaces, of which the following is a specification.

This invention has reference to garbage incinerators for furnaces and its object is to provide for the economical disposal of garbage by providing an incinerating apparatus which may be made a part of a heating furnace, so that the heat needed for the incineration of the garbage is utilized for other purposes.

In accordance with the present invention an incinerating vessel is provided and so constructed as to be lodged in the fire pot and extend into the ash pit of a heating furnace such as is customarily employed for heating dwellings, and provision is made for the use of gas as a fuel both for the destruction of the garbage and for heating purposes, so that in warm or mild weather only sufficient gas is employed to effect the incineration of the garbage, while in colder weather additional heat may be obtained as needed. By this means the heat needed to destroy the garbage is utilized for heating the dwelling when such heating is desired.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that while the drawings show a practical form of the invention, the lattery is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications come within the scope of the appended claims.

In the drawings Figure 1 is a front to rear vertical section ofa heating furnace with the garbage incinerator installed. Fig. 2 is a front to rear sectional elevation of the heating elements of the incinerator and furnace. Fig. 3 is a plan view of the grate structure with distant parts omitted and showing some parts in cross section. Fig. 4 is a section on the line lf-4 of Fig. 2, but omitting some distant parts. Fig. 5 is a section on the line 5 5 of Fig. 4, but drawn on a larger scale. Fig. 6 is a detail view of one ,Si of the burner caps.

.Referring t .the drawings there is shown a furnace 1 which may be taken as indicative of any suitable type of domestic heating furnace which in the drawings is indicated as a hot air furnace, although, of course, other types of furnaces may be utilized.

The furnace is shown as provided with the usual lire pot 2 and fire chamber 3, as well as ash pit 4 and the lire chamber is also shown as provided with the customary chute with its door 6, while the ash pit has the usual duct 7 and door 8. Since all these parts may follow the usual practice it is unnecessary to give any specific detailed description thereof. It is to be understood, however, that the usual grate forming the bottom of the fire pot is omitted.

In accordance with the present invention there is provided a ring 9 mounted upon legs 10 of su'flicient length to elevate the ring for a distance above the bottom of the ash pit, but at a less height than the bottom of the fire pot. Entering the ash pit through the duct 7 is a pipe 11 carried to a point centrally of the ring 9 and there rising through the ring and coupled to a distributing chamber 12 from which radiate pipes 13 of sufficient length to extend beyond the ring 9, upon which ring the pipes 13 are supported. Outside the ring 9 each pipe 13 carries a burner unit 14: in the form of a curved duct 15 having its curvature on an axis coincident with the center of the chamber 12, said chamber being cylindrical. The duct 15 has formed on it a number of burner members 16 which in the particular showing `of the drawings are four in number, there being two burner members 16 on each side of the pipe 13 which is connected to the duct l15 midway of the length of the latter. Each burner member 16 is of substantially even diameter throughout and freely open at the top and is there interiorly beveled as indicated at 17 to seat a burner cap 18. This cap is shown separately in Fig. 6 and is of substantially the same form for all burners. The cap is formed with a circular series of outwardly `flaring grooves 19 and with a circular series of positioning lugs 20 adapted to enter the burner member 16, while centrally through the cap is a passage 21. Each burner member 16 has an inset 22 at one side with a perforation therethrough, while each cap member 1S has a corresponding perforation so that a headed pin 23, which may be an ordinary wire nail .Of Suitable size, is passed through the per-A forations and bent over in the inset 22 to hold the burner cap 18 in place.

The top of the chamber 12 is in the form of a diaphragm 24 which is held in place by another cylindrical chamber 25 secured to the chamber 12 by screws 26 extending through lugs 27,y 28 on the two chambers 12 and 25, respectively. Radiating from `the chamber 25 are short nipples 29 each carrying a burner 'unit 30 comprising two burner members 31 similar to the burner members 16, so that the burner units 30 form a circular series of burners similar to the burner members 14, vbut interior to the latter, although arranged at a somewhat greaterheight from the bottom of the furnace. Each burner member 31 has an inset 32 like the inset 22 of the burner members 16 and each burner member 31 is provided with an interior bevel 33 for a burner cap 18 held by a pin 23 in the same manner as already described.

The chamber 25 is closed 'by an integral top 34 with a central passage suitably tapped to receive the threaded end of a burner member 35 similar to the burner members 16 and 31 in that its upper end is beveled as shown at 36 and is there closed by a burner cap 18a similar in all respects to the burner caps 18, except that there is no passage for a pin 23 provided. Instead the burner cap 18 is held by a headed pin 23a similar to the pins 23 exceptas to length and in this instance the pin .23a extends through the .passage 21 and is bent about the lower end of the burner member 35 to hold the cap in place. r1`he chamber 25 is entered by a pipe 37 directed through the duct 7 to the exterior of the furnace.

Carried by the ring 9 and pipes 13 is a casing 38 of general cylindrical form except that it is cut away, as indicated at 39, to provide for the pipe 37 and for another pipe 40 having numerous perforations 41 so as to permit the lighting 'of gas, issuing from the various burners, from the eXterior of the furnace.

Carried by the upper edge of the casing 38 is an annular grate 42 comprising a ring c 43 with an annular groove 44 in one edge entered by the upper edge of the casing 38, and from vthe ring extend radial grate fingers 45. The grate ring 43 and fingers 45 are of a size to lill in 'the space between the inner walls of the fire pot and the casing 38 and parts thereabove.

The grate ring 43 on the edge remote from the groove 44 is provided with another annular groove 46 in which is seated a ring 47 constituting a continuation of the casing 38. Supported by the ring 47 is another ring 48 having an annular groove 49 into which the corresponding edge of the ring 47 enters. The upper edge of the .ring 48 is provided with a similar groove '50 in which is seated the lower end of a cylindrical casing 51 rising through the fire pot into the lire chamber and terminating about level with or-a little below the chute 5. The ring 48 is also a grate ring extending toward the center of the casing 51, which latter constitutes the incinerating chamber for garbage and 4other refuse. The grate carried bythe ring 48 is provided with another ring 52 interior to and concentric with the ring 48 and having an annular groove 53 in its upper edge. The groove 53 is entered. by lugs 54 on a circular shaker grate 55 movable close to and above the grate 48. The shaker grate is provided with a central upstanding hollow post 56 rising to a point above the incinerato-r casing 5land there .provided `with a cross coupling 57 in line with the chute 5 and door 6, so that a bar, indicated in dotted lines at 58, maybe inserted in the coupling to impart rotative movements to the grate for shaking the latter, 'while 'the hollow ypost 56 provides a draft passage when thecasing 51 is lled with garbage or other refuse.

Fast to the inner wall of thecasing 51 is a series of longitudinal tapering ribs 59 widening toward the bottom of the casing and stopping short of the shaking grate 55, the purpose of these ribs being to prevent garbage vor other refuse placed in the casing during the incineration from initially settling down and compacting at the botto-m of the casing. This is due to the gradual taper of lthe free interior of theV casing because of the gradual approach of the inner edges of the ribs `as they near the grate.

Lodged on the annular grate 42 within the fire pot 2 is a quantity of fragments 6() of refractory material, such as broken fire brick or the like.

Garbage is introduced into the incinerating casing 51 through the door 6 and chute 5, but in order to prevent the material from dropping into the fire pot upon the broken brick 60 a guide plate or apron61 is introduced through the chute 5, so `as to rest upon the upper edge of the casing 51, while a guard plate 62 surrounds the upper end of the casing 51. Garbage is thereby directed into the casing 51 without liability of any of it reaching the fire chamber outside of the -incinerating casing.

If it be assumed that it is desired to burn the garbage at a time of year wheny the heat of the furnace is not desired, the inner set of burners 31 are lighted, this being readily controlled because the pipes 11 and 37 are separate. Garbage lodged on the shaker grate 55 or grate 48 is subjected to the heat of the gas issuing from the burners 31 and 35, and such heating being sufficiently in` tense quickly reduces the garbage to ashes, which on the shaking of the grate 55 are broken up and fall into the ash pit. When,

yso

however, the Weather may be cool enough to demand a furnace fire, the burner units 111 are brought into service, gas being supplied through the pipe 11, and the gas may be lighted by the lighting pipe 40 as before. The flames issuing from the burner members 16 serve to heat the broken brick 60 and keep such brick in a glowing condition simulating a bed of burning coal and the heat thus produced is utilized for the heating of air in the furnace 1 to be directed through the dwelling. The heat thus provided is suflicient to incine ate garbage within the casing 51, or this garbage may be more quickly incinerated by utilizing the set of burners within the casing 5l.

The garbage incinerator may be installed in the furnace when first set up or may be applied to coal or gas burning furnaces already in use. A furnace provided with the incinerator attachment is more economical to operate than two distinct devices for the purpose, while the heat generated in the incinerating operation may be utilized for the heating of the dwelling in which the device is located.

Gas entering the chamber 25 through the pipe 37 is liable to find its way to the burner on the opposite side of the chamber to the partial exclusion of the other burners fed from the chamber, wherefore a deflector strip 63 is made fast to a portion of the inner wall of the chamber in the line of flow of gas entering through the pipe 37, so that the progress of the gas is retarded sufficiently to cause a substantially even distribution to the several burners 31 and 35.
